Patent CA-2155198-A1 (CA)
Title: Method and apparatus for separation by flotation
Inventor: CHUDACEK MICHAEL
IPC: B03D1/14
Filed: 1994-01-20
Abstract: A suitably conditioned slurry feed is introduced to a trough (1) from which it is distributed into a slurry layer-flow forming chamber (2). Chamber (2) is provided with a discharge weir (3) which discharges an evenly spread layer of slurry (4) onto an inclined plate (5) feeding into a mixing passage (6). Recirculated slurry from vessel (7) is also fed into mixing passage (6) via a recycle gate (8) which forms it into a layer of slurry (9). An array of clean liquid jets (12) accelerates thin gas envelopes and impinges between layers of slurry (4) and (9) causing intensive mixing of all streams in mixing passage (6). The high shear rate produces high intensity turbulence and shears gas into very small bubbles. A multiphase mixture flow is discharged from mixing passage (6) into vessel (7), where it flows past one or more longitudinal stabilizing baffles (13). Gas bubbles loaded with hydrophobic particles disengage from the stream, rise towards the liquid surface and are diverted by bubble diverting guides (14) towards the froth discharge end of the vessel. A layer of froth travels towards froth weir (15) where it is discharged.  The residual slurry leaves discharge launder (19) via a weir (20) to the next flotation cell or process stage.

Title: System and method for automatic page registration and automatic zone detection during forms processing
Inventor: RANGARAJAN VIJAYAKUMAR
IPC: G06V30/10
Filed: 1996-04-10
Abstract: A system and method automatically detect user defined zones in a document image of a form, compensating for skew and displacement of the image with inspect to an original image of form. The system provides a mechanism to input an image for a form document, such as a scanner. The system processes the image to reduce its resolution and to remove significant skew. The image is presented to the user to define the zones. These zones are areas from which the user desires to extract meaningful data through optical character recognition, such as names, dates, addresses, and items on an invoice form. The system further processes the image to remove horizontal and vertical lines, and to create a number of blocks, representing either text or image data. The lines are removed and the blocks form by runlength smoothing with various parameters. The blocks form clusters of connected pixels. The blocks are labeled such that any set of connected blocks share a unique identification value. Additional data is collected on the commonly labeled blocks to select those blocks useful to definition of a template. The template is a collection of vectors between the centroids of each of the selected blocks. A second document image for processing is obtained, and similarly processed to minimize, deskew, and identify blocks and vectors therein. The vectors in the second document image are compared with vectors in a user selected template to determine the location of user defined zones in the second document image.

Abstract: Complexones having the structure of N-2-(azol-1(2)-yl)ethyliminodiacetic acids, synthesis, analytical study and biological applications, characterized by their complexing capacity over Ca2+, Mg2+ ions and other bivalent cations, lanthanides and transition metals. In the formula azolN-CH2CH2-N (CH2CO2R)2 (I), azol is pirazol; 3,5-dimethylpirazol; indazol; etc. and R is alkyl or H or Na. The compounds having the general formula (I), are obtained by an alkylation reaction of methyl iminodiacetate with N-bromoethylazols and further hydrolysis in acid or basic medium. The process may be modified by alternative synthetic processes which involve N-aminoethylazols as starting materials or the use of cyclization processes in the preparation of Nsusbtituted azol. They can be applied in spectroscopy and nuclear magnetic resonance (NMR) imaging of hydrogen or other nuclei as extrinsic probes of Ca2+, Mg2+ or other metal ions and as contrast agents, in solutions, biological extracts, tissues, entire animals and human beings.
